主　　题：high power input coupler fabrication superconducting cavity 

摘      要：The BEPCII storage ring adopts two 500 MHz superconducting cavities （SCC）. Each one is equipped with a 500 MHz input power coupler. The coupler is to feed 150 kW power in continuous wave （CW） mode with both standing and traveling wave modes. Due to high power feeding and high frequency of the coupler, its fabrication is a big challenge. The fabrication started with two key components, the window and the antenna. Up to now, two sets including windows and antennas have been made by IHEP. And a 270 kW RF power in CW has passed through the coupler during the high power test. The fabrication details are presented in this paper.
